RELATED FACTORS OF TIC SEVERITY IN THE YALE GLOBAL TIC SEVERITY SCALE (YGTSS)
Main Article Content
Abstract
The study was carried out with the objective of analyzing some related factors of the severity of tics according to the Yale Global Tic Severity Scale (YGTSS). This is a cross-sectional descriptive study, included 77 children who came to outpatient unit of Department of Psychiatry, National Children’s Hospital for the first time, and were diagnosed with Tourette syndrome (F95.2). The results show that majority of tics onset in children under the age of seven (62.3%) and was diagnosed at the age of 8-11 years old (55.8%). Most children were male (88.3%), the male/female ratio was 7.5/1 (p<0.01). Antibiotic use, father’s age and mother’s age were significantly related to the severity of tic according to the YGTSS scale in the linear regression model. Specifically, the risk of YGTSS score went up by 1.6 points when the age of fathers increased by one year. The age of mothers increased by one year led the risk of YGTSS score went up by 1.7 points. Mothers who used antibiotics during pregnancy had an increase of risk of YGTSS score by 25.8 points. There was no relationship between the birth order of children, delivery with intervention, gestational age, birth weight with the YGTSS score. There was no relationship between other independent variables including children's stress, first symptoms, ADHD, OCD, developmental delay, anxiety disorders, number of tics with YGTSS scores in the linear regression model.
